Hillary Clinton’s Tuesday appearance on The Daily Show failed to provide any clarity on whether she will run for President, despite host Jon Stewart’s best attempts.

“She’s here solely for one reason: to publicly and definitively declare her candidacy for President of the United States,” Stewart said jokingly when introducing Clinton. But the best he could coax out of the former Secretary of State and First Lady was that speculation on her candidacy had turned into a “cottage industry.”

Clinton's appearance on The Daily Show comes near the end of a book tour that has taken her across the U.S., to Europe and to the studios of most major American television networks for extended interviews. It is a return performance for Clinton, who first appeared on Stewart's Comedy Central show when she was a Senator for New York promoting her 2003 memoir, Living History. She also made an appearance during her 2008 presidential campaign.

During Tuesday’s show, Clinton touched on several of the domestic and international issues she tackled as Secretary of State, topics that are the backbone of her latest book, Hard Choices, which currently occupies the No. 2 slot on the New York Times’ nonfiction best-seller list.

Stewart called the book an “eyewitness view to the history of those four years,” but repeatedly came back to the question of 2016. “I think I speak for everybody when I say, no one cares (about the book), they just want to know if you’re running for President.”

On that point, however, Clinton intends to keep feeding that cottage industry.
